MOLDER' S FLASK.

I I Specification of Letters Patent. 7

Patented Nov. 28,1916.

Application filed October 22, 1914. Serial No. 838,052.

To all whom it may concern Be it known that 1, WILLIAM 'L. JULIEN, a citizen of the United States, residing at Dayton, in the county of Montgomery and.

while rigidly held in place when mounted in the flask are interchangeable, and may be formed to the proper required length.

With other objects in view, which will be referred to, my invention consists in the peculiar combination and novel arrangement of parts, such as will behereinafter more fully described in connection with the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view in top plan of a fragmentary portion of the side of the flask with my invention applied thereto. Fig. 2 is a transverse sectional view taken on the line 22 of Fig. 1. Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 1 and looking in the direction indicated by the arrow. Fig. 4: is a fragmentary perspective view of the shaped end of the bar and the tapered wedge adapted to Work in connection therewith. Fig. 5

is a view in rear elevation of a section of the rail.

The flask in its body portion may be of the standard form and construction, comprising the side members 1 which are made to the desired length and are held together in any approved manner, these side members having a plurality of orifices 2 provided through the body portion thereof and at a point preferably adjacent the lower ed e.

d rail 3 is fitted to the inner surface of the side member 1 of the flask and this rail has the chipping strip 1 provided on the contacting face thereof to permit a better fitting of the two members. Bolts 5 or other suitable securing means are passed throu h the rail 3 and through the orifices 2 to ho d the rail rigidly secured to the member 1 of the flask and on the outer face of the rail member 3 a plurality of dove-tailed recesses 6 is formed at suitably spaced apart intervals to lie in a vertical plane and have a gradual divergent taper from the upper to the lower end.

I The flaskb'ars -7 are made in'cross section in the form of an inverted wedge and at their inner ends these bars 7 are shaped, as are better illustrated in Fig. 41, to fitat their one side within the dove-tailed recesses 6 and at the opposite side to'present a flat and vertically extended face. This shaped end at 8 is made dove-tailed on the one side and is received against the one side of the recess 6 after which the taper key 9 which is shaped to have the one side thereof conform to the dove-tailed recess and the opposite side to'conform to the flat surface 10 of the shaped end 8 of the bar .is inserted in the clearance between this. surfaced end and the open side of the dove-tailed recess and the bar is thus wedged and rigidly secured in place. These flask bars 7 may be made of any length and may be extended in an oflset relation substantially the entire distance across the flask, the length of extent depending in a great measure upon the specific application and use, however, it is perhaps preferable that the bars 7 be made of a length to extend inwardly from the sides of the flask to a point near the pattern used in the molders flask.

The outer end of each of the bars 7 is beveled as at 11 and at intervals along the extent of the bar the V-shaped grooves 12 are formed on each side thereof to extend parallel with the beveled end 11 and to perunit ready severance of the bar at the point marked by the V-shaped grooves so that the bars when manufactured may be made of a uniform length and as working conditions require may be severed at one of the points marked to procure the proper length. If i desired the openings 13 may be provided in the extent of the bars 7 to receive the usual rods and thus the flask may be used in any 7 connection that a flask requires.

From the foregoing it will be seen that I have provided a flask in which the .bars are formed to be of one length and as conditions require may be shaped to the desired length.

While I have herein shown and described one specific form of my invention, it will be understood that slight changes might be made in the form and arrangement of the several parts of the structure without departing from the spirit and scope of my invention, and hence I do not wish to be limited thereto except for such limitations as the claims may import.

I claim 1. A molders flask comprising sides having vertically extending dove-tailed and tapered recesses, flask bars shaped at one end on one face to fit and hold in the dovetailed recesses and on the opposite face made plain, and means to be wedged between the plain face and the open side of the dovetailed recess to secure the flask bar in a rigid mounting.

2. A molders flask comprising in combination with side members and rails secured tically extending dove-tailed tapered recesses, flask bars shaped at one end on the one face to fit and hold within the dovetailed recesses and on the opposite face made plain and a tapered key shaped to be received against said face and within the dove-tailed recesses to hold the flask bars rigidly secured in place.

3. As an article of manufacture, a flask bar adapted to be used in connection with a flask having a plurality of dove-tailed and tapered recesses for the feception of said bars and wedges to secure the same in place, said bar comprising a body portion shaped to the desired form and design and having an end thereof shaped on the one side to be received Within and fit one of the side walls of the dovetailed and tapered recess and the opposite face shaped to have bearing of the wedge thereagainst as the parts are mounted in the operative relation.

In testimony whereof I affix my signature Copies of this patent may be obtained for five cents each, by addressing the Commissioner of latents, Washington, D. G.
